Dude, that thing is thrashed. I wouldn't pay anywhere near $750 for it. If it was actually worth it, don't you think another movie theater would have bought it up? That thing looks like it was dug up out of someone's backyard.

Unfortunately it wouldn't work very effeciently in a living room and you'd need a serious amp to drive it properly. Modern subs are designed to effeciently produce bass in a living room whereas that Cerwin Vega box needs a large room to work properly.
